Rolls-Royce has updated the Cullinan SUV, six years after its launch with new styling, an overhauled interior, updated technology and with a special focus on offering extensive personalisation options. Rolls-Royce describes it as "the most extensive Series II development in Rolls-Royce history."

1. Cullinan facelift gets updated fascia; new bumper, headlamps
2. Interior gets latest 'Spirit' OS that debuted on Spectre 
3. Retains 6.75-litre, twin-turbo V12 engine

Rolls Royce Cullinan Series II design

The front of the Cullinan has been restyled with new LED daytime running lights that extend till the bumper. The lower bumper arrangement is also angled at the sides.

The grille has been given a new look too: it is now framed at the top and bottom by horizontal chrome bars and a new protruding edge below gives the impression that it is sitting atop a plinth. Plus, it now lights up for the first time.

There is a new feature line on the side, running from the brake light to the middle of the rear wheel, and the rear valance now kicks up at the back and is painted gloss black. A new rear bumper rounds off the body design changes, incorporating a stainless-steel skid plate. The aluminium wheels are one inch larger than before, at 23 inches.

The Cullinan Black Badge is more differentiated from the standard car now, with black door handles, colour-coded lower bodywork and a bespoke treatment for the air intakes.

The headline upgrade inside is the introduction of a full-width glass panel across the dashboard, with an illuminated cityscape motif in front of the passenger, like that in the Spectre. Another highlight is the new display 'cabinet' in the dash, which houses an intricately detailed analogue clock and a miniaturised, stainless steel version of the Spirit of Ecstasy mascot under it.

Rolls says this took four years to develop, and necessitated "a unique partnership between analogue and digital craftspeople to create a dramatic and meticulously orchestrated flow of light".

The Cullinan also gains the latest version of Rolls' Spirit infotainment system, which brings new graphics and displays. It also enables personalisation to the extent that owners can change the colours of their instruments to match the paintwork or upholstery. The new version of Spirit also includes Rolls-Royce's dedicated members' app, Whispers, which allows users to lock the car, set destinations and monitor location using their phone.

Rolls-Royce's increasingly lucrative personalisation offering has been expanded with the introduction of a raft of new paint and material options. Highlights include 'Grey Stained Ash', a metallic-effect open-pore wood trim; Duality Twill, an intricately patterned seat fabric made of bamboo fibres; and perforated leather upholstery.

Under the hood, the Cullinan remains mechanically unchanged, which means it continues to be powered by a 6.75-litre, twin-turbocharged V12 engine that’s mated to an 8-speed torque converter automatic gearbox sending power to all four wheels. In the regular Cullinan, this engine produces 571hp and 850Nm of torque, while it produces 600hp and 900Nm in Black Badge-spec.
